The present invention provides a method for producing a 12-membered ring macrolide compound expected as a prophylactic or therapeutic agent for solid tumors and the like, and a production intermediate thereof. In detail, by acetalizing hydroxyl groups at 6- and 7-positions of a 12-membered ring macrolide compound being a raw material with dialkyl tin (IV) oxide and, after that, reacting the product with a carbamoyl halide derivative, the 7-position urethane derivative of the 12-membered ring macrolide compound being the target is effectively produced, without protecting hydroxyl groups at other positions.
